The sweetest words for me are those said spontaneously...delivered with the right emotional feeling, and an effortless tone. I could list certain sentiments that I have used, but removed from their context, I think they lose a lot of their meaning...

Having said that, telling someone youcan't wait to warm them up always seems to fit the moment.
